I have a usb which is capable of storing the iso (before you might ask me).
To cut a long story short, I basically destroyed windows vista on my pc (oops) and now I have a windows 7 iso (which I downloaded, non pirated so it should run well) and I got my windows activation key from the side of my pc. But since im new to ubuntu (I literally know nothing, no seriously I know NOTHING) I don't know how I could burn the iso onto my usb and make sure it actually runs. So how can I do it (without using anything else beside my computer that only runs ubuntu? Please simplify things if you are gonna explain, my mind already hurts from reading the basics of ubuntu terminal commands.
